#ARDUINO MEGA RAMPS 1.4 PINOUT CODE#

There is no purge block, but I wanted to see how fast the switch is possible. T15 to switch to another tool (mixing colors ratios) for each plate: Which gave me plates-16.gcode which I edited and inserted the “16 colors palette” Gcode, and after each “WALL-INNER” lines I added T0, T1 etc.

Extruder 1 (E0 or A): glowing magenta PLAĪs such I prepared 16x 20×20 plates with 1 layer height: print3r -printer=ashtar-k-2-e3 -slicer=cura -random-placement -scad -multiply-part=16 -output=plates-16.gcode slice 'cube()'.

I used following code to purge 30mm (10+10+10mm) filament from all 3 colors at once at the very beginning ( start_gcode): M165 A0.33 B0.33 C0.33 1/3 for each filamentĪdditionally, define the firmware retraction: M207 F3000 S4 Z0.3 set firmware retraction 50mm/s 4mm, 0.3mm zhop The following ( source) defines 16 different mix ratios of common colors with Cyan, Yellow and Magenta: CyanĪfter that, the virtual tools T0 – T15 are available, printing different mix ratios. Within ~/.config/print3r/printer/ashtar-k-2-e3.ini I added in start_gcode different palettes: Trinary PaletteĪ general palette of 19 mixed colors using 3 colors defined in Gcode: M163 S0 P1Īfter that, the virtual tools T0 – T18 are available, printing different mix ratios.

M163/M164: define mixing ratio palette and define a virtual tool per mixing ratio which can be used as “T” in Gcode later.

In case the Extruder #3 (E2) runs reverse, invert it in Configuration.h: #define INVERT_E2_DIR true Mixed Colors Prints #define RETRACT_RECOVER_FEEDRATE_SWAP 8 // Default feedrate for recovering from swap retraction (mm/s)Īdd following lines below E1_CS_PIN: #define E2_STEP_PIN 58 #define RETRACT_RECOVER_FEEDRATE 8 // Default feedrate for recovering from retraction (mm/s) #define RETRACT_RECOVER_LENGTH_SWAP 0 // Default additional swap recover length (mm, added to retract length when recovering from extruder change) #define RETRACT_RECOVER_LENGTH 0 // Default additional recover length (mm, added to retract length when recovering) #define RETRACT_ZLIFT 0 // Default retract Z-lift

#define MAX_AUTORETRACT 10.0 // Upper limit for auto-retract conversion #define MIN_AUTORETRACT 0.1 // When auto-retract is on, convert E moves of this length and over Use E0 for Extruder #1, E1 for Extruder #2, and use an Stepper Extender for Extruder #3:Įnable FWRETRACT: #define FWRETRACT // ONLY PARTIALLY TESTED #define DIRECT_MIXING_IN_G1 // Allow ABCDHI mix factors in G1 movement commands #define MIXING_VIRTUAL_TOOLS 32 // Use the Virtual Tool method with M163 and M164 #define MIXING_STEPPERS 3 // Number of steppers in your mixing extruder * - Enable DIRECT_MIXING_IN_G1 for Pia Taubert's reference implementation * - This implementation supports only a single extruder. * - Optional support for Repetier Firmware M163, M164, and virtual extruder. * - Extends the stepping routines to move multiple steppers in proportion to the mix. * - Adds a new code, M165, to set the current mix factors. In the Marlin following settings are required:Ĭounter intuitively using 3 extruders with single nozzle in mixing operations, keep EXTRUDERS 1 and do not enable SINGLENOZZLE but leave is disabled.

I print with Ashtar K #1 and #2 since a couple of months and since about 4 months with Ashtar C #1successfully, and thought to convert Ashtar K #2 (300×300 build-plate) with a Diamond Hotend with 3 colors/extruders, renamed to “ Ashtar K E3“:Ĭyan, Yellow, Glowing Magenta, Cyan Z-transition Firmware (Marlin) & Hardware (RAMPS 1.4) 2: added Firmware Retraction changes in Marlin, updated Trinary Color Palette.5: 16 palette mixed colors from cyan, yellow and glowing magenta (CMY) photo added, best result of mixing colors.
